The lenght of the boom between the rear reflector and the rear dipole is more than enough to get the needed counterweight. Drill a hole into the boom and slip into it a bolt passing through the conterweight and put again the reflector into the original hole. 73" de i8CVS Domenico _______________________________________________ Sent via amsat...@amsat.org.
